(well i think its a great idea)....(imagine this is what steve jobs would say when introducing the new iTunes)..."We have ratings, so you can rate your songs and organize them...5 stars, 4 stars, but these get out-dated. You might think a song is 5 stars but a month down the track you don't think it is worth of 5 stars anymore. Wouldn't it be nice if iTunes just figured out what your 5 stars were and then kept updating them so a month later they were automatically changed to 4 or 3 stars. Well, now you can. In iTunes you can set a preference so that if you play a song a certain number of time in one week, or day it automatically becomes 5 star, and you can set these up for all the different stars. So you could set it to make it if you don't listen to a song for 6 months it goes down to 1 star etc." he then shows an example "BOOM" what do you think.
